Application filed November 4. 1020 To a whom it may manor Be it knownthat I, HENRY ZIEMSH. Jr. a eitizen of the United States, residing atChicago. in the eounty of (look and State of lllinoie. have inventedcertain new and weful Improvements in Brake-Realm. at whieh thefollowing is a specitieation.

This invention relates to hralt beams for railway cars, the object beingto improve the eonstruetion 0f the hrake head.

The hrake head may comprise a. fare it having llangw 13 at its sides.and a huh lt lying het ween $llltl flanges. 'l'he flange. 13 may haveopenings 17 therein adapted to r eeive the usual hanger.

I realizethat various moditi -ations may he made within the spirit and scope ofthe invention, and I therefore do not limit myself to the exactconstruction shown and described.

I claim as my invention:

1. A brake head comprising a hub having an inclined slot thereinextending around a portion of its Wall, said slot forming a springclamping portion which is wider at its base or attached end than at itsopposite end.

2. A brake head comprising a hub having two inclined converging slotstherein, said slots forming between them a central spring clampingportion, said slots also forming a spring clamping portion at each sideof said central clamping portion, said hub having longitudinal slotscutting one end of each clamping portion from the body of the hub.

3. A brake head comprising a hub provided with two spring clampingportions, one of said clamping portions having its base or attached endat one side of the hub, and the other clamping portion having its baseor attached end at the opposite side of the hub.

4. A brake head comprising a hub having a central spring clam ingportion and an oppositely extending cliamping portion comprising twoparts lying at opposite sides of the central portion.

5. A brake head comprising a hub having a slot extending around aportion of its wall, said slot forming two spring clamping portions.

6. A brake head comprising a hub haw ing a transverse slot, said slotforming two spring clamping portions, said hub having longitudinal slotscutting opposite ends of said portions from the body of the hub.

7. A brake head comprising a hub having a transverse slot in its wall toform two hub portions, one of said portions being connected to the bodyof the hub at one end of said slot, and the other portion beingconnected to the body of the hub at the other end of said slot.

8. A brake head comprising a hub having two transverse slots in itswall, said slots forming a central hub portion, and a hub portioncomprising two parts lying at opposite sides of the central hub portion,

I body at the said central portion being connected to the hub body atone end of said slots, and said other portion being connected to the hubopposite end of said slots.

9. A brake head comprising a hub having a slot running transverselythrough its wall to form two portions of the hub, a hangerattaching eye,webs connecting said eye with one portion of said hub, said webs formingbetween them a slot connecting the interior of the hub with the interiorof the eye, the other portion of the hub having a longitudinal slottherein at the opposite side of the hub from said hanger-attaching eye,a web on said other portion at one side of said slot, and a web on thehub body at the other side of said slot.

10. A brake head comprising a hub having oppositely extending springclamping portions, an angular web at the free end of each of saidportions, webs on the body of the hub lying alongside the first mentioned webs, and means for drawing the pairs of webs together.

11. A brake head comprising av hub slotted to form oppositely extendingspring clamping portions connected at one end to the hub body, ahanger-attaching eye integral with the hub body and with the one end ofone of said portions, and means for drawing the end of the other portiontoward the adjacent part of the hub body.

12. A brake head comprising a hub rircumferentially slotted to form aentral spri g clamping portion, and a spring clamping portion comprisingtwo parts lying at opposite sides of said central portion, each of saidlatter parts being connected at one end to the hub body; a web at oneend of one of said portions, a web on the hub body lying alongside thefirst web, a hanger-attaching eye integral with said webs, a Webconnecting the ends of the parts of the other one of said portions, aweb on the hub body lying alongside the last m ntioned web, and meansfor clamping the two last mentioned webs together.

In testimony whereof I affix my signature in presence of two witnesses.
